23688-89-3 - Introduction
acid is an organic compound with the chemical formula C5H3ClN2O2. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
acid is a white crystalline solid with a special smell. It is soluble in ethanol and chloroform at room temperature and slightly soluble in water.
Use:
acid is often used as an intermediate in organic synthesis and can be used to synthesize other organic compounds. It also has some applications in the field of medicinal chemistry, such as the synthesis of certain antibiotics and heterocyclic compounds.
Method:
The preparation of hydrochloric acid is generally carried out by esterification of chloropyrazine and bromoacetic acid. The specific steps are as follows: reacting chloropyrazine with bromoacetic acid in an organic solvent, then adding excess sodium hydroxide solution for neutralization, then acidifying with acid, and finally obtaining the target product through crystallization or extraction purification.
Safety Information:
acid generally does not cause obvious harm to the human body under normal operating conditions. However, as a chemical raw material and intermediate, it is still necessary to comply with safe operating procedures when using and preparing, avoid contact with skin and eyes, and ensure operation in a well-ventilated place. Seek immediate medical help if touched or taken by mistake.
